Gold mine flotation production

Gold mine flotation process

The flotation of gold minerals generally adopts a grinding-flotation process. For the ore with uneven grain size, a stage grinding process can be used. In China, a one-stage grinding-flotation process is generally used to achieve the enrichment of useful minerals.

Grinding fineness requirements for gold mines

The requirement of fineness of gold ore grinding generally requires that the gold encapsulated in the sulfide mineral only dissociates from the sulfide ore monomer, but the fineness of the gold that is associated with the gangue needs to reach the monomer of gold. Dissociation. At the same time, the fineness of grinding of a certain mineral is determined by experiment.

Gold mine flotation process slurry concentration requirements

The principle of gold mine flotation is: flotation of large density, coarse grain minerals, often with more concentrated pulp; conversely, when flotation of small density, fine grain size and slime, use thinner pulp, thicker thicker The pulp can guarantee a higher recovery rate, and the selection of the dilute concentration is conducive to improving the quality of the concentrate.

Other process conditions

In addition to the fineness of grinding, the process conditions affecting the gold flotation also include the concentration of the slurry, the amount of flotation agent, the amount of aeration, and the flotation time.
